Detailed Description

So that those skilled in the art can better understand the technical solution of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 6, the embodiment of the utility model discloses a cast in situ concrete stair formwork, including die block 4, step facade template unit 6 and side form unit 3, have a plurality of step facades on the die block 4 for a plurality of step facade template units 6 are placed in the laminating, and two side form unit 3 parallel relative settings set up in the relative both sides of die block 4, and every step facade template unit 6 all can be dismantled and connect between two side form units 3. The independent prefabricated module of step facade template unit 6 self need not relapse the dismouting in the use, has effectively improved and has used turnover number of times.

In this embodiment, the step vertical face formwork unit 6 includes a wood formwork 61 and square timber 62, the two wood formworks 61 are arranged in parallel and oppositely, and the two square timber 62 are arranged between the two wood formworks 61 up and down and are connected with the wood formworks 61. The two square timbers 62 are spaced by a certain distance and used for connecting the step vertical face template unit 6 between the side template units 3 by penetrating the pull rod 1, so that the disassembly is more convenient.

In this embodiment, the side mold unit 3 includes an inner wood side mold 32 and an outer wood side mold 31 which are attached to each other, and a plurality of slots 33 are formed in the top of the inner wood side mold 32 along the length direction for inserting the end portions of the step facade template unit 6, so that a structural form capable of being spliced and inserted is formed between the step facade template unit 6 and the side mold unit 3, and repeated measurement and positioning are not needed. The size of the groove 33 on the inner wood side die 32 is consistent with the size of the cross section of the step facade template unit 6, and the groove 33 can ensure that the facade template unit 6 is stable when concrete is poured.

In this embodiment, the outside of side form unit 3 is connected with two flitches 2, and the flitch 2 is connected with interior wood side form 32 and outer wood side form 31 through the iron nail, and two flitches 2 relative up-down set up and the certain distance of interval for wear to establish pull rod 1, and fasten through clamp plate 5. Two square timbers 2 are as the atress roof beam, and the structure is more firm.

The utility model provides a cast in situ concrete stair formwork takes off the off-site centralized processing when the construction, then the reinforcement is assembled on the scene: firstly, the number of the step facade template units 6 and the size of the groove 33 of the side template unit 3 are lofted and processed according to a drawing; secondly, the number of the pull rods 1 is calculated according to the length of the stairs, the concrete flow state of the step plane needs to be noticed in the concrete pouring process, and all the surfaces in contact with the concrete are coated with a release agent; thirdly, the reinforcing support of the stair bottom die 4 needs to be calculated to ensure the stability of the support.

The utility model provides a cast in situ concrete stair formwork compares with conventional formwork in the past, has following beneficial effect:

1. the step facade template unit 6 and the side template unit 3 are manufactured independently, and are not repeatedly reinforced by iron nails, so that the template loss is reduced, repeated disassembly and assembly are not needed, the turnover frequency of materials is greatly improved, and the materials are saved.

2. The off-site centralized processing and on-site assembly are adopted, so that the construction efficiency is high, the on-site cross interference is avoided, and the labor is saved.

3. Through the pull rod reinforcement, convenient dismantlement.

4. The units are made of wood materials, construction is light, installation and fixation are not needed to be carried out, excessive reinforcement is not needed to be arranged on the step surface, and the quality of the step concrete collecting surface can be guaranteed.

4. The construction is safe, and the requirements of site construction are met.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims.
